The canopic jars of Rameses II: real use revealed by molecular study of organic residues

Four blue-glazed faience jars, on exhibition in the Louvre Museum, are referred to as the canopic jars of Rameses II. Their recent typological re-examination rendered this original assignment questionable. In order to clearly determine their use, a study of two successive organic residues from the canopic jars, using molecular biomarkers analysed by GC-MS and LC-MS and absolute dating by ¹⁴C, was initiated. The results revealed that these two materials were not contemporary to the reign of Rameses II. The first one, scraped from the interior face of one jar, was identified as an unguent made of coniferous oil and animal fat and dated from the Third Intermediate Period. The second one, originally stored with glued linen inside one jar, is likely an embalming substance, made of pure vegetable resin (Pistacia) and dated from the Ptolemaic Period. These results clarify a controversy which has been lasting over a century. The famous blue-glazed faience jars are not the canopic jars of Rameses II but are confirmed as situlae which were reused at least two times: first to store unguents during the Intermediate Period and later to store embalming packages of an unknown person during the Ptolemaic period.     

EMERGENCE OF LEAPFROGGING FROM RESIDENTIAL CHOICE WITH ENDOGENOUS GREEN SPACE: ANALYTICAL RESULTS

Leapfrog development is a typical form of sprawl. This paper aims at analyzing the existence, size, and persistence of leapfrogging in a dynamic urban economic model with endogenous green amenities. We analyze whether incoming households choose to settle at the fringe of the city or to jump further away depending on their preferences and the structure of the city. We first provide an analytical treatment of the conditions and characteristics under which a first leapfrog occurs and show how the optimal choice is affected by the size of the city, income, commuting costs, as well as the size of the area where green amenities are considered. We then study how further leapfrogging and multiple urban rings may appear and be maintained in the long‐run equilibrium, and how infill processes take place through time.     

The Role of Engineer-in-Chief and the Introduction of Foreign Hydraulic Dredging Technology and River Conservancy into China, 1890s–1930s

This paper discusses studies of the development of river conservancy in modern China, and the role of engineers-in-chief in river improvement planning on rivers such as the Hai-ho (Haihe) and the Whangpoo (Huangpu). It discusses the introduction of foreign hydraulic dredging technology and management into two major Chinese ports. It then analyses the process by which two agencies of the Chinese government absorbed and adjusted this technology to suit local circumstances in the treaty ports of Tianjin and Shanghai beginning in the 1890s. Without prior experience in river conservancy, the conservancy boards adopted a range of foreign technologies. This allowed them to develop into major institutions that facilitated increasing trade flows between China and the rest of the world. Of particular significance in this process of technological change was the role of the expatriate engineers-in-chief who were employed as chief executive officers of both agencies. They were responsible for establishing the operations of the agencies, accommodating an increasing range of responsibilities such as financial and human resource management, and training Chinese engineers and managers for senior positions until they were ready to replace the expatriate engineers-in-chief after the 1930s.     

Intensification in the city centre: Barriers to implementation in Regina,Saskatchewan

As cities aim for more sustainable patterns of urbanization, intensification has emerged as a core planning strategy. In 2013, the City of Regina set new intensification targets: absorb 30% of annual population growth through intensification and add 10,000 residents to the city centre by 2035. In the decade since, implementation has been unsuccessful. This study explores the barriers to core area intensification in Regina by engaging with key informants through semi-structured interviews. Our findings identify the most significant barriers as soft market demand, a city centre that is unappealing as a residential context, insufficient political will, an absence of developers who specialize in core area intensification, and unfavourable development economics. These findings illustrate the unique challenges faced by mid-size Canadian cites in disrupting entrenched development patterns and driving development towards the downtown.     

Differences in cancer incidence between men and women in the province of Québec, Canada, 1984–1993

This research concerns variation in incidence rates of cancer for males and females aged 35 to 69 in Québec for the period 1984 to 1993. In analysing the data, the Island of Montréal (health region 06) was distinguished from the rest of the province of Québec (excluding Nunavik and the James Bay regions). Relative rate index and the ratio of standardised incidence rates of cancer for males and females showed similar tendencies in all regions studied, with the risk of non–sex‐specific cancer higher in men than in women (excess ranged from 5 or 20 to 240 percent according to the study region). However, this higher risk was not consistent across lifespan and cancer site in the Montréal area. We suggest some general points that could explain the differences in cancer incidence between males and females.
